Which of the statements are true in regards to stress/strain transformation? (Please select all statements that are true? ) Group of answer choices An element can be oriented at a point so that the element's deformation is caused only by normal strains with no shear strain. When the state of strain is represented by the maximum in-plane shear strain, there is no normal strain acting on the element. The element representing the maximum in-plane shear strain and its associated average normal strain is 90 from the element representing the principal strains. Six stress components depend upon the orientation of the element. The state of plane stress at a point is uniquely represented by 3 components acting on an element that has a specific orientation at the point
